We are now using a new music file format that gives us a clearer, crisper and stronger sound. You may notice a volume difference if you are mixing music from R1-16 with music from older sets. We apologize if this causes you an inconvenience but you will see that the quality of the music playback is much better.

There are several things that you can do to minimize adjusting volume while teaching your classes. If you are using iTunes, be sure you turn on the Sound Check feature. This is meant to adjust the volume on all of your music playback to as close to the same level as possible. Here’s how to do that:

Open iTunes.

On the top menu bar in the top left, click on Edit, then on Preferences.

In the dialog box that appears, click on Playback in the top menu bar.

In the top third of the screen, put a check mark in the box next to Sound Check.

Click OK at the bottom of the screen to save this change.

You can also adjust the volume of individual songs. Here are the steps:

Open iTunes.

Find the song you want to adjust. Right click on the title.

From the menu that opens, choose Get Info.

From the menu bar at the top choose Options.

Look for the Volume Adjust in the center of the page. You can increase or decrease the volume of the song by moving the slider forward for more volume, back for less.

Under the Volume Adjuster is an Equalizer. You can choose between the selections offered there to modify other parts of the music for your individual taste.

Please note that if you have used the individual volume adjust on some of your music, the Sound Check option will not work on them. It will not override the adjustments you have made. If you want Sound Check to work correctly, it may be necessary to change the volume and equalizer on any songs you have modified back to the default or None position on both items.

You will need to experiment a bit and see which options work best for your preference. Again, we apologize for this inconvenience, but hope you will hear the noticeable difference in the quality of music you are now receiving from us.
